  • A field experiment was conducted in Agronomy farm at an altitude of 1350 m. above sea level in a randomized complete block design with three replications and eight treatments on vegetable type soybean in 2005. The objective was to see the effect of vermicompost alone and in combination with Rhizobium inoculum and mineral fertilizers on the yield of vegetable soybean. The result showed higher number of nodules from the non inoculated plot, however, the nodules weight was highest from the inoculated plots. No significant difference was notice statistically on roots and shoots dry weight. Soybean grain was obtained highest (32.3%) over the non inoculated plot followed by vermicompost plus inoculated, however, there was non significant difference. There was a slight increment on grain and straw yield from the inoculated plots over the non inoculated.

  • A Haematococcus pluvialis strain isolated from the ruins of Ephesus in Turkey was investigated as regards its adaptation to laboratory conditions and maximum growth rate. In the first stage of the experiment, the growth of H. pluvialis was compared in common culture media. Furthermore, in an effort to minimize the culture costs, the second stage of the experiment compared the growth rate in the culture medium selected in the first stage with that in commercial plant fertilizers. The results demonstrated that the maximum cell concentration of 0.90 g/l, corresponding to a growth rate of $0.150d^{-1}$, was found with an N-P-K 20:20:20 fertilizer under a light intensity of $75{\mu}mol$ photons $m^{-2}s{-1}$ on the $12^{th}$ day of cultivation.

  • We investigated concentrations and loads of nutrients in the paddy plots with conventional and environmental paddy plots in Chungbuk. Different fertilizers for basa dressing were applied to two paddy plots. There were not significantly different concentrations between two experimental paddy plots because almost same amount of fertilizers were applied to two plots. For drainage water during rainy days mean T-N concentration was lower, but mean T-P concentration was almost identical compared with respective values in flooded water.

  • This paper is an experimental arrangement developed by the author to test certain theories relative to stimulating plant growth in a electro-magnetic field. It was the invention and use of cheap chemical fertiliazers that effectively suppressed electro-cultural engineering. Today, however, we are in the position where nitrate pollution by these very fertilizers threaten not only our water supply but the entire ecological pancrama as well. Thus it would appear that the revival of electro-culture is not only desirable but imminently necessary.

  • The effects of media, cell sizes and fertilizers on the early growth of Phalaenopsis plug plants were investigate. The sphagnum moss was more effective than other media in pink and white color cultivars. In comparison of different plug cell size, 50 cell size was more effective then 72 and 128 cell size in pink and white cultivar. In comparison of different fertilizer, margamf K in pink, and nutrient solution II(one time drenching with NHRI standard solution for three times irrigation) in white color cultivars was more effective then others, respectively.

  • In these experiments Gamiojeoksan remnant components were analyzed to recycle this medicinal herb remnant fertilizers. The basic growth of Korean mint by application of Gamiojeoksan remnants were higher than control. As the amount of fertilizers were increased, plant height, stem diameter, number of leaves and number of branches were increased. The growth and yield were the highest in the treatment of 30 g/pot. Weight of whole plant of Korean mint has a tendency to be heavy in application of herbs remnant than that of control.

  • Customary agriculture seeks to increase production and supply people with safe foods. Thus. the promotion and establishment of organic agriculture are required to reduce water and soil pollution caused by customary agriculture. Although organic agriculture is an agricultural technology system whose basic principle is organic water circulation in agronomic agriculture and livestock industry. the livestock raising sector has not been developed in Korean organic agriculture: hence the limited development of agronomic agriculture. This study therefore sought to develop a standardized model connected with organic livestock raising and organic agronomic agriculture to secure symmetric and continued development. Specifically, this study reviewed the technological and economic problems related to the development of a naturally circular standard model where organic agronomic agriculture and organic livestock raising are connected. Likewise, a model for calculating the appropriate quantity of fertilizers to be applied and appropriate number of livestock to be bred was proposed as important factors in the development of a regionally circular agriculture model, and an alternative to a system connecting the two factors suggested.

  • To find out the best complex fertilizer for high yielding of rapeseed crop, experiment was conducted on complex fertilizers at the experiment field in upland of rapeseed in Mokpo Experiment Station, Nat'l Institute of Corp Science, RDA, Korea. Experiment was laid out in randomized complete block (RCBD) design. The effects of complex fertilizer (22-22-11) on the number of branches, pod length, percentage of seed set and seed yield were highest but on the plant height, ear length, and number of pods per ear were negligible. On th basis of the results reported above, for getting higher yield of rapeseed crop, among the tested fertilizers complex fertilizer (22-22-11) gave the superior performance and is recommended for application.

  • Nanotechnology is considered the most important technological advancement in recent years, and it is utilized in all industries due to its potential applications. Almost all of the industries (food, agriculture, medicine, automotive, information and communication technologies, energy, textile, construction, etc.) reorganize their future in the light of nanotechnological developments. As the most important source of income of countries, the agriculture industry increases the use of nanotechnology products gradually as a solution to the problems encountered. Reducing the use of agricultural inputs (pesticides, herbicides, fertilizers, etc.) by increasing their efficiency utilizing nano-carriers, detecting the environmental conditions and development of the crops in the field simultaneously by making use of nanosensors, reducing the sample volume and the amount of analyte used thanks to nanoarrays, effective treatment of water resources through nano-filters, accelerating the development of crops by using nanoparticles are the prominent nanotechnological applications in the agriculture industry. This review presents information on the benefits of the recent developments in nanotechnology applications in the agriculture industry.

  • To find out the optimum fertilizer level for high yielding variety, Paldanghomil, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage rye in Sunchon National University from Sep. 1998 to Aug. 1999. The effects of nitrogen fertilizer on plant growth were large significant but increasing rate of application in potassium and phosphate fertilizers above 10kg/10a had negligible effects on plant growth. Raising nitrogen application rate of fertilizers turned out to be 18-10-10kg/l0a of N-P$_2$O$_{5}$-K$_2$O. Content of crude protein was the highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate. Furthermore, IVDMD was high and dry matter yield were the highest at the optimum rate.e.
